Subject: drm/i915: ELiminate intel_pipe_to_cpu_transcoder() from
assert_fdi_tx()

Git-commit: a722146b5f52f514aabf0d04c3dbdd39850d0a8c
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Let's start to eliminate intel_pipe_to_cpu_transcoder() so that
we can get rid of one more crtc->config usage (which we will want
to nuke as well).
In the case of assert_fdi_tx() we know that we're never
dealing with the EDP transcoder so we can simply replace
this with a cast.
